Description of Development of a low cost technology for in-situ treatment of groundwater for potable and irrigation purposes (TiPOT) (2004 - 2007)

In surface science there is great effort to move from studying simple, flat model surfaces in vacuum to investigating more complex model catalysts in gas environments (in situ). This thesis gives three examples of such studies using microscopy and spectroscopy.

In this dissertation iron-based homogeneous catalysts were synthesized, characterized and investigated for water oxidation activity.

The dissertation describes TEM experiments on heterogeneous catalysts.

Large parts of the research described in this Thesis aims at the development of oligopeptide-masked toxins and their in situ immunoproteasome-mediated activation.

Molecular complexes can be used as electrocatalysts for oxygen reduction, water oxidation, and/or hydrogen peroxide production.

The work described in this dissertation contributes to a better mechanistic understanding of nanoparticles in vivo. To achieve that goal, we used the zebrafish as a highly predictive pre-screening model of nanoparticles.

Boek- en kunsthistorica en promovenda Daphne Wouts heeft een bijzondere ontdekking gedaan. In het Westfries Archief in Hoorn vond ze op drie oude stukken papier twee boekenlijsten van de Enkhuizer Librije uit 1634 en 1649. Het Noordhollands Dagblad schreef een artikel over haar bijzondere ontdekking…

There are many interpretations of quantum mechanics, and ultimately experiments are needed to verify or falsify these interpretations.

We investigate the buildup of galaxies from various vantage points. The first two chapters focus on the stellar content of galaxies, especially the distribution of stellar masses at birth and potential variations therein in various galactic environments.

We have examined sequences from the ligand-binding domain of the nicotinic acetyl choline receptor (nAChR) in 148 vertebrate species. We are in interested in this receptor because the α-neurotoxins of many venomous snakes binds to this receptor in its location at the neuromuscular junction in all ve…

Hoe kunnen dure en zeldzame materialen beter worden gebruikt om schonere brandstof goedkoper te produceren? Onder leiding van Marc Koper, hoogleraar katalyse en oppervlaktechemie, publiceren internationale teams van wetenschappers 3 publicaties in Nature Communications.

Marc Koper heeft de Netherlands Catalysis and Chemistry Award ontvangen tijdens de 20e bijeenkomst van de Netherlands' Catalysis and Chemistry Conference. ‘De ultieme kandidaat voor deze prijs’, zo valt te lezen in een van de aanbevelingsbrieven.

Synthetische brandstof is schoner dan natuurlijke olie, maar het productieproces is nog niet efficiënt genoeg. Nu hebben wetenschappers voor het eerst direct de moleculen waargenomen die uit het chemische proces ontstaan. Het opent de deur richting efficiënte ‘designer’ katalysatoren. Publicatie op…
